Mersen 20308 Class H/K Fuse Block – 3-Pole, 30A, 250V AC/DC, Box Lug Terminal, UPC: 782001758592

The 20308 is an open-style fuse block built on a durable glass-filled polycarbonate (GFPC) base. It features high-conductivity tin-plated copper alloy contacts with spring-reinforced clips to ensure a reliable connection. Because it is a Class H/K block, it is used primarily in applications where extremely high short-circuit current ratings are not required (typically rated for 10kA to 50kA depending on the fuse used).
